[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings to make the advantages and features of the present invention easier to understand by those skilled in the art. Obviously, the embodiments described in this application are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0031] See also Figures 1 to 3 The feeding device shown in the figure includes a fixed frame 100 and a transmission mechanism disposed on the fixed frame 100. A material belt 10 is disposed on the transmission mechanism so as to be movable along its length. The material is attached to the surface of the material belt 10 and is transported by the transmission belt 10. The transmission mechanism includes a swing seat 11, on which are disposed a stripping member 12 and a sticking member 13. The stripping member 12 has a feed surface 121 and a discharge surface 122 disposed opposite to each other. Figure 8 As shown, the feed surface 121 and the discharge surface 122 are connected to form a stripping end 123 that can peel the material from the material strip 10. The material strip 10 passes through the feed surface 121, the stripping end 123, and the discharge surface 122 in the longitudinal direction. The attachment 13 is spaced apart from the feed surface 121 to form a passage for the material strip 10 to pass through. The attachment 13 at least partially overhangs one side of the stripping end 123.

[0032] In this embodiment, after the material strip 10 passes through the stripping end 123, the material is stripped from the material strip 10. At this point, the material can be attached to the product by driving the feeding device and the product closer together. Then, by driving the feeding device and the product in relative motion, the attachment 13 can press the material and adhere it to the product surface. This allows the feeding device to not only transfer the material but also attach it. In this embodiment, the attachment 13 is cantilevered from the stripping end 123 to prevent the stripping end 123 from interfering with the attachment 13's pressing operation.

[0033] In this embodiment, the swing seat 11 includes a connecting end 111 and a swinging end 112 spaced apart. The connecting end 111 is rotatably mounted on the fixed frame 100 about a first rotational centerline X1, which is parallel to the width of the material strip 10. The stripping member 12 and the attachment member 13 are both mounted on the swinging end 112. In this embodiment, the feeding device further includes an adjustment mechanism 14 for adjusting the position of the swing seat 11 on the fixed frame 100. The adjustment mechanism 14 is connected between the swing seat 11 and the fixed frame 100. Rotating the swing seat 11 via the adjustment mechanism 14 not only drives the stripping end 123 and the attachment member 13 to rotate, thereby adjusting their angles to achieve different material attachment operations. Furthermore, the distance between the attachment member 13 and the product can be adjusted to adjust the pressing force applied by the attachment member 13 to the material and product. Furthermore, the swing seat 11 can be rotated to maintain tension on the material stripping and attachment operations, ensuring proper performance.

[0034] In this embodiment, the material strip 10 located on one side of the feed surface 121 is transported along a first direction, and the material strip 10 located on the side of the discharge surface 122 is transported along a second direction. The first and second directions intersect, and the stripping end 123 abuts against the material strip 10. This forms a corner at the stripping end 123 of the material strip 10. Due to the different stiffnesses of the material and the material strip 10, the material can be peeled off the material strip 10 as it passes through the stripping end 123. Specifically, the material strip 10 has a first side surface and a second side surface, which are located on opposite sides of the thickness direction. The material is located on the first side surface, and the stripping end 123 abuts against the second side surface. In this embodiment, the feed surface 121 and the discharge surface 122 form an acute angle, making it easier to peel the material from the material strip 10.

[0035] See also Figure 8 As shown, in this embodiment, the stripping member 12 is wedge-shaped, and the tip of the wedge constitutes a stripping end 123. The second side surface of the strip 10 abuts against the tip. The two side surfaces of the stripping member 12 in the thickness direction respectively constitute a feeding surface 121 and a discharging surface 122. The feeding surface 121 and the discharging surface 122 are arranged near the tip. Figures 6 to 8 As shown in the figure, the feeding surface 121 faces upward and the discharging surface 122 faces downward.

[0036] In some embodiments, the material belt 10 does not contact the feed surface 121 and the discharge surface 122 when passing through them, or does not completely adhere to the feed surface 121 and the discharge surface 122 during transmission. Preferably, the first direction is parallel to the extension direction of the feed surface 121, and the second direction is parallel to the extension direction of the discharge surface 122. More preferably, the material belt 10 is transmitted closely to the feed surface 121 and the discharge surface 122 to ensure a high success rate in material peeling.

[0037] In this embodiment, the stripping member 12 also has a plate-like structure extending away from the stripping end 123, which is used to improve the stability of the connection between the stripping member 12 and the swing seat 11, and can form an extended surface connected to the feeding surface 121 and extending away from the stripping end 123, providing better guidance for the transmission of the material belt 10 along the first direction to the stripping end 123, ensuring that the material belt 10 can be transmitted stably and ensuring the stripping rate of the material.

[0038] See also Figure 8 As shown, in this embodiment, the stripping element 12 is equipped with a stopper 16, located on one side of the feed surface 121. The stopper 16 can be adjusted parallel to the width of the strip 10. The stopper 16 is used to limit the displacement of the strip 10 along the width, preventing it from moving along the width and thereby improving the accuracy of the material attachment. By adjusting the position of the stopper 16, the width of the channel between the stripping end 123 and the attachment attachment 13 can be varied to accommodate strips 10 of varying widths.

[0039] In this embodiment, the feeding device includes a pressing roller rotatably mounted on a swinging base 11. The pressing roller forms a laminating member 13, and the axis of the pressing roller is parallel to the first rotational centerline X1. The pressing roller is driven to press the material against the product and roll it relative to the product, thereby rolling the material and achieving lamination.

[0040] In this embodiment, the adjustment mechanism 14 has a movably arranged driving member 141, and the driving member 141 is rotatably connected to the swing seat 11 around the second rotation center line X2. By driving the driving member 141 to move, the swing seat 11 can be driven to rotate. In some embodiments, the driving member 141 is movably arranged on the fixed frame 100. Specifically, the adjustment mechanism 14 includes a cylinder 142, and the driving member 141 is driven by the cylinder 142 to move. In this embodiment, the cylinder 142 is connected to the fixed frame 100 through a cross bar 143. The axis of the cross bar 143 is parallel to the first rotation center line X1. The angle of the cylinder 142 can be adjusted by driving the cylinder 142 to rotate around the axis of the cross bar 143 to adapt to different working scenarios. In some embodiments, the driving member 141 can be set to a telescopic length, and the position of the swing seat 11 can be adjusted by telescopic length. Specifically, the driving member 141 is the telescopic shaft of the cylinder 142.

[0041] In this embodiment, the feeding device includes a guide roller 15 rotatably mounted on a swinging base 11. The material strip 10 is sequentially wound along its length around the guide roller 15, the material feed surface 121, and the material stripping end 123. The material strip 10 is tensioned between the guide roller 15 and the material stripping end 123. The axis of the guide roller 15 is parallel to the first rotational centerline X1. The guide roller 15 guides the material strip 10, ensuring that the material strip 10 between the guide roller 15 and the material stripping end 123 is transported in the first direction. Preferably, the guide roller 15 keeps the material strip 10 in close contact with the material feed surface 121.

[0042] In this embodiment, the peeling member 12 and the attachment member 13 are adjustable in position along a first direction, so that the relative position relationship between the peeling member 12 and the attachment member 13 can be adjusted as needed to adapt to different usage scenarios. Specifically, the swing seat 11 has two mounting plates 113 spaced apart along the width extension direction of the material strip 10, the guide roller 15 is rotatably disposed between the two mounting plates 113, the peeling member 12 is mounted between the two mounting plates 113, and the ends of the attachment member 13 are respectively connected to the two mounting plates 113 via connecting members 17, and the attachment member 13 is rotatably disposed between the two connecting members 17. The two sides of the peeling member 12 are mated with the two mounting plates 113 via a sliding groove structure, and the two connecting members 17 are mated with the two mounting plates 113 via the sliding groove structure. Locking assemblies are provided between the side of the peeling member 12 and the mounting plate 113, and between the connecting member 17 and the mounting plate 113, respectively, for locking the peeling member 12 and the mounting plate 113, respectively. When the lock between the peeling member 12 and the mounting plate 113 is released, the two can be driven to slide relative to each other, thereby adjusting the position of the peeling member 12. When the lock between the connecting member 17 and the mounting plate 113 is released, the two can be driven to slide relative to each other, thereby adjusting the position of the attachment 13. In this embodiment, the locking assembly includes a locking hole and a locking pin that can be inserted into the locking hole.

[0043] In this embodiment, the swing seat 11 includes a connecting plate 114 connected between the two mounting plates 113 , and the driving member 141 is rotatably connected to the connecting plate 114 around the second rotation center line.

[0044] In this embodiment, the transmission mechanism includes a floating roller 51, which is mounted on a fixed frame 100 and is rotatable and capable of sliding up and down. The web 10 passes beneath the floating roller 51, which supports the web 10. When the tension of the web 10 changes, the floating roller 51 moves up and down. For example, when the web 10 slackens, the support force exerted by the web 10 on the floating roller 51 decreases, causing the floating roller 51 to move downward under the force of gravity. The tension of the web 10 can be determined by detecting the position of the floating roller 51. Furthermore, as the floating roller 51 moves downward, it can move the web 10 downward, thereby alleviating the slack in the web 10 and tightening it.

[0045] In this embodiment, the transmission mechanism includes a driving roller 41 and a driven roller 42. The driving roller 41 is rotatably mounted on a fixed frame 100, while the driven roller 42 is rotatably mounted on the fixed frame 100. The material strip 10 passes between the driving roller 41 and the driven roller 42. The transmission mechanism also includes a drive assembly 43 for driving the driving roller 41 to rotate. The driving roller 41 can provide a torque force to transport the material strip 10 forward. By clamping the material strip 10 between the driving roller 41 and the driven roller 42, the driving roller 41 drives the unloaded material strip 10 to be transported forward.

[0046] In this embodiment, the feeding device includes a loading mechanism 2 and a receiving mechanism 3. The loading mechanism 2 is used to provide a material strip 10 with material attached thereto, and the receiving mechanism 3 is used to recycle the material strip 10. The material strip 10 is transferred from the loading mechanism 2 to the receiving mechanism 3. Specifically, the receiving mechanism 3 includes a receiving shaft 31, which is rotatably mounted on a fixed frame 100. The transmission mechanism includes a drive mechanism 32 for driving the receiving shaft 31 to rotate. The material strip 10 is connected to the receiving shaft 31 and can be wound around it. By driving the receiving shaft 31 to rotate, the material strip 10 is driven forward. The receiving mechanism 3 also provides the torque required to transfer the material strip 10.

[0047] In this embodiment, the torque of the transmission strip 10 is adjusted by cooperating with the material receiving mechanism 3, so that the strip 10 is in a stretched state. Specifically, in this embodiment, the driven roller 42 can be arranged on the fixed frame 100 relatively away from or close to the active roller 41. The driven roller 42 has a first position and a second position. When in the first position, the driven roller 42 is close to the active roller 41, and the strip 10 is clamped between the active roller 41 and the driven roller 42. The active roller 41 participates in and provides the torque transmitted by the strip 10. When the driven roller 42 is in the second position, the driven roller 42 is away from the active roller 41. The distance between the driven roller 42 and the active roller 41 is greater than the thickness of the strip 10, so that the strip 10 is separated from the active roller 41, and the active roller 41 does not participate in providing the torque transmitted by the strip 10.

[0048] In this embodiment, the feeding device is equipped with a detection mechanism 52 for detecting whether the position of the floating roller 51 has changed. The feeding device is also equipped with a conversion mechanism 44 for driving the driven roller 42 to move between a first position and a second position. The detection mechanism 52 is signal-connected to the conversion mechanism 44. When the detection mechanism 52 detects movement of the floating roller 51, it sends a signal to the conversion mechanism 44. Based on the received signal, the conversion mechanism 44 drives the driven roller 42 to adjust between the first and second positions. Specifically, the floating roller 51 has a warning height relative to the fixed frame 100. When the detection mechanism 52 detects that the height of the floating roller 51 is below the warning height, indicating that the material strip 10 has slackened, the detection mechanism 52 sends a signal to the conversion mechanism 44. The conversion mechanism 44 drives the driven roller 42 from the second position to the first position, thereby enabling the active roller 41 to participate in providing torque and thereby coordinating the slack of the material strip 10.

[0049] In this embodiment, the web 10 passes along its length, sequentially passing through the swing seat 11, between the active roller 41 and the driven roller 42, and through the floating roller 51, ultimately reaching the receiving mechanism 3. The floating roller 51 can promptly detect any slack in the web 10 caused by insufficient torque, and can also promptly detect the adjustment of the web 10 after the active roller 41 has provided torque. In this embodiment, the swing seat 11, the active roller 41, and the floating roller 51 function in a synergistic manner. When the swing seat 11 is driven to adjust the contact angle or contact force, if the tension or slack of the web 10 changes, the floating roller 51 or the active roller 41 can promptly adjust the web 10.

[0050] In this embodiment, the active roller 41 is located below the driven roller 42. The driven roller 42 is mounted on the fixed frame 100 and can move up and down. The conversion mechanism 44 is used to drive the driven roller 42 to move up and down. In this embodiment, the conversion mechanism 44 includes an electric cylinder, and the driven roller 42 is driven by the electric cylinder to move up and down.

[0051] In this embodiment, the fixed frame 100 is provided with a guide rail 110 extending in the vertical direction. The feeding device is provided with a sliding member 120, which is slidably mounted on the guide rail 110. The floating roller 51 is rotatably connected to the sliding member 120. In this embodiment, two floating rollers 51 are provided. The material strip 10 passes under the two floating rollers 51 in sequence along its length. The two floating rollers 51 are arranged to move synchronously in the vertical direction. Figure 2 、 Figure 3 As shown, in this embodiment, two floating rollers 51 are rotatably connected to the sliding member 120. The provision of two floating rollers 51 can provide more sufficient tensioning force and can also respond more quickly to the relaxation of the material strip 10.

[0052] In this embodiment, the feeding device is provided with a clamping mechanism 6, which is located upstream of the swing seat 11 along the length of the material strip. Specifically, the clamping mechanism 6 is located between the feeding mechanism 2 and the swing seat 11. The clamping mechanism 6 includes a first roller 61 and a second roller 62, which are rotatably mounted on a fixed frame 100, and the material strip 10 passes between the first roller 61 and the second roller 62. In the clamping state, the material strip 10 is clamped between the first roller 61 and the second roller 62. This not only smoothes the material strip 10 for subsequent stripping and attaching operations, but also applies resistance to the movement of the material strip 10 to maintain its tension.

[0053] In this embodiment, the first roller 61 is eccentrically mounted on the fixed frame 100 and rotates around the first rotation axis, and the second roller 62 is eccentrically mounted on the fixed frame 100 and rotates around the second rotation axis. As the first roller 61 rotates eccentrically, the clamping mechanism 6 periodically switches to a clamped state. Specifically, the feeding device includes an eccentric shaft 63 mounted on the fixed frame 100, and the first roller 61 is movably mounted on the eccentric shaft 63 and can rotate eccentrically around the eccentric shaft 63. In this embodiment, the axis of the second roller 62 extends colinearly with the second rotation axis. In some embodiments, the second roller 62 can also be eccentrically mounted. Specifically, see Figure 4 As shown, the fixing frame 100 includes a frame body and a fixing plate 130 . The fixing plate 130 is spaced apart from the frame body of the fixing frame 100 . The first roller 61 and the second roller 62 are rotatably disposed between the frame body of the fixing frame 100 and the fixing plate 130 .

[0054] In this embodiment, the eccentric shaft 63 is rotatably mounted on the fixed frame 100 about a first rotation axis. By rotating the eccentric shaft 63, the eccentric angle of the first roller 61 can be adjusted, thereby adjusting the distance between the first roller 61 and the second roller 62 when in the clamped state. This is to accommodate material strips 10 of varying thicknesses or material strips 10 carrying materials of varying thicknesses. In this embodiment, a locking mechanism is provided between the eccentric shaft 63 and the fixed frame 100. The locking mechanism includes a locking member 641 fixedly mounted to the eccentric shaft 63. When the locking mechanism is in the locked state, the locking member 641 engages with the fixed frame 100 to lock the eccentric shaft 63 relative to the fixed frame 100. When the locking mechanism is in the unlocked state, the locking member 641 disengages from the fixed frame 100, allowing the eccentric shaft 63 to rotate relative to the fixed frame 100.

[0055] In this embodiment, the feeding device includes a rotating handle 64 for driving the eccentric shaft 63 to rotate. The rotating handle 64 is fixedly connected to the eccentric shaft 63. The operator can rotate the rotating handle 64 to drive the eccentric shaft 63 to rotate, thereby adjusting the eccentricity of the first roller 61. Figure 4 、 Figure 5 As shown, the locking member 641 is fixedly mounted on the rotating handle 64 and extends from the rotating handle 64 toward the fixing frame 100. In this embodiment, the locking mechanism includes a locking slot 140 disposed on the fixing frame 100. When the locking mechanism is in a locked state, the locking member 641 is inserted into the locking slot 140, and when the locking mechanism is in an unlocked state, the locking member 641 is disengaged from the locking slot 140.

[0056] Specifically, the fixing plate 130 is provided with a plurality of locking slots 140, and the eccentric shaft 63 is also axially slidably disposed on the fixing frame 100, and the eccentric shaft 63 can be driven to slide by rotating the handle 64. As the rotating handle 64 slides axially along the eccentric shaft 63, the locking member 641 fixed to the rotating handle 64 can move relatively away from or relatively close to the fixing plate 130, thereby being inserted into or disengaged from the locking slot 140. In this embodiment, when adjusting the spacing between the first roller 61 and the second roller 62, the rotating handle 64 is pulled away from the fixing frame 100, causing the locking member 641 to disengage from the locking slot 140, thereby releasing the lock between the eccentric shaft 63 and the fixing frame 100. Then, the eccentric shaft 63 is driven to rotate by rotating the handle 64. When it rotates to the expected position and the locking piece 641 corresponds to the position of another locking groove 140, the rotating handle 64 is pushed toward the fixing frame 100 so that the locking piece 641 is inserted into the locking groove 140, and the eccentric shaft 63 and the fixing frame 100 are locked with each other.

[0057] In this embodiment, the feeding mechanism 2 includes an expansion shaft 21 rotatably mounted on the fixing frame 100 , and a material tray wound with the material strip 10 is sleeved and fixed on the expansion shaft 21 .

[0058] In this embodiment, the feeding device includes a tensioning roller 7, which is rotatably mounted on a fixed frame 100. In this embodiment, a plurality of tensioning rollers 7 are provided, and the tensioning rollers 7 are arranged in the transmission path of the material belt 10. The material belt 10 abuts against the tensioning rollers 7, which, on the one hand, provides a guide for the transmission of the material belt 10, and on the other hand, keeps the material belt 10 in a tensioned state. Figures 1 to 3 As shown, the tension roller 7 is disposed between the feeding mechanism 2 and the swing seat 11, between the swing seat 11 and the active roller shaft 41, and between the active roller shaft 41 and the floating roller shaft 51. In this embodiment, the axis of the tension roller 7, the axis of the expansion shaft 21, the axis of the active roller shaft 41, the axis of the driven roller shaft 42, the axis of the floating roller shaft 51, and the axis of the receiving shaft 31 are parallel to each other and parallel to the width extension direction of the material strip 10.

[0059] In this embodiment, the material is a label or a film that can be attached to the surface of the material strip 10 .

[0060] In this embodiment of the feeding device, the material strip 10 moves longitudinally from the loading mechanism 2 through the clamping mechanism 6, guide rollers 15, the channel between the self-adhesive attachment 13 and the feeding surface 121, and then passes through the stripping end 123, the discharge surface 122, between the active and passive rollers 41 and 42, and beneath the floating roller 51, ultimately reaching the receiving mechanism 3. The feeding device integrates both material conveying and material application, using the attachment 13 to tightly adhere the material to the product. The rotatable swing seat 11 allows for adjustment of the application angle and application force, allowing the feeding device to adapt to different scenarios. The feeding device is provided with an active roller 41 and a material receiving mechanism 3, two mechanisms that can provide torque for transmitting the material belt 10, and is provided with a floating roller 51 to detect the degree of slackness or tension of the material belt 10. According to the position change of the floating roller 51, the driven roller 42 is driven to switch between the first position and the second position, so that the torque transmitted by the material belt 10 is regulated by the active roller 41, so that the material belt 10 is in a tensioned state, thereby ensuring the stability of the feeding device.
